PT can be utilized to evaluate magnetic and nonmagnetic materials, unlike Magnetic Particle Examination.


And also, PT can locate flaws in materials with detailed frameworks. Liquid Penetrant Evaluation has constraints though. This is because of the fact that only superficial flaws can be found. Furthermore, proper pre and post-inspection cleaning is needed for this welding assessment. Both internal and exterior faults can be found with ultrasonic screening, often known as UT weld evaluation.

Occasionally, it might be required to test the WPS credentials by performing tests on weld vouchers (test pieces). Verifying the base metal and welding consumables compliance with the applicable specs. Examining for joint cleanliness and appropriate fit-up. Making sure that the joint layout and weld preparation is certified with the WPS and suitable welding requirements (ASME, AWS, API).




Occasionally, pre-welding examination may find abnormalities that are within code constraints however can present a problem at a later phase in production. That's why it's vital for the welding examiner to be acquainted with the entire manufacturing procedure and to be experienced with the welded tools. Assessment during the welding procedure is vital for spotting the weld defects and stopping a wrong welding strategy from creating large weld beings rejected throughout the entire job.
